Brushless motor controller used friends have this kind of feeling, mostly other brushless motor controller, at the same level within the outer rotor and rotor current compare, will find external rotor torque motor controller, to some 'hard', inner rotor torque motor controller slightly smaller, 'soft' to some, a look at the motor controller parameters, exterior rotor motor controller KV value of more than 800, more than 1000 to more than 2000 inner rotor motor controller. Look again at speed, the rotating speed of rotor motor controller was obviously higher than that of external rotor motor controller. Actually these traits are related with the KV value, as defined by the KV value to explain, the idling speed brushless motor controller, is KV value multiplied by the input voltage, this also explains why the speed of the inner rotor motor controller is higher than the exterior rotor brushless motor controller. Dantian = motor controller work design inside the static design departments outside the outside outer = motor controller of lateral use iron permanent magnet dc motor controller is designed particularly high energy saving, high efficiency especially speed (Up to several times than iron)3 -Reduce weight a third - 50000 are not particularly itselfIt should be said that acura 2/5. Transfer principle of inside and outside surface no difference between electromagnetic structure surface with wind turbine sector outside lead structure is then the product phase are converted to see parts supply conditions on dantian high-speed won by some other advantages. Inner rotor and outer rotor of the fan has a lot of, exterior rotor motor control is used on the fan noise is small, the fan long time running between have a better life. Outer fan can do too dantian fan air volume, mainly based on fan impeller shaft as the motor controller and base (The shell)Who turn to determine: 1, the fan impeller with spindle motor controller called turn frame fixed period fan motor controller. 2, fan fan impeller outer motor controller as motor controller housing the rotating spindle fixed outer fan motor controller. 3, make structure more compact outer fan as used for occasion in vane double suction fan.
